Boromir is a fictional character in J. R. R. Tolkien's legendarium. He appears in the first two volumes of The Lord of the Rings (The Fellowship of the Ring and The Two Towers), and is mentioned in the last volume, The Return of the King. He was the heir of Denethor II (the 26th Steward of Gondor) and the elder brother of Faramir. In the course of the story Boromir joined the Fellowship of the Ring.
Boromir is portrayed as a noble character who believed passionately in the greatness of his kingdom and fought indomitably for it. His great stamina and physical strength, together with a forceful and commanding personality, made him a widely admired commander in Gondor's army and the favourite of his father Denethor. As a member of the Fellowship, his desperation to save his country ultimately drove him to betray his companions and attempt to seize the Ring, but he was redeemed by his repentance and brave last stand.
Commentators have remarked on Boromir's vainglory and desire for the Ring. They have compared him both to other proud Tolkien characters such as Fëanor and Túrin Turambar, and to medieval heroes like Roland, who also blew a horn in battle and was killed in the wilderness. His boat-funeral, too, has been likened to Scyld Scefing's ship-burial in Beowulf.
Boromir appears in animated and live-action films of Lord of the Rings, and in radio and television versions.
